More particularly, the invention relates to a roller coating cavity adaptable for feeding a coating material or the like to a roller brush when using a pump or the like.

PREVIOUS TECHNIQUE The roller coating device has been used in several fields. The roller coating device is used in an automotive manufacturing industry, for example. In industry, the roller coating device is used to form a protective film on a surface of a car coating film in order to protect the coating film against rainwater, iron dust, pollen, bird droppings and the similar and thereafter to prevent deterioration of coating quality. - 2 - In the known roller coating device, the roller is manually rotated in a container of coating material containing a coating material, and the coating material infiltrates the roller. This method is difficult in the uniform application of the coating material on the entire roller, resulting in an unusual coating of the coating material on the roller. Such a process is repeated that the coating material is applied to the roller several times and then the coating material again infiltrates the roller. This process includes several problems: do you need more hours of? man, more processing costs and more hours of work, and extension of the coating booth. In this situation, an apparatus was developed which automatically suppresses the coating material of the containers of coating material to the roller by the use of a pump. Was a material feeding apparatus also developed? Automatic coating that can handle a high viscosity coating material. In addition, this feeding apparatus is reduced in size. One of the latest models of this type of roller coating device is "Roller Coating Device", submitted by the Applicant for this Patent Application in the form of an attached application (Patent Document 1).

Patent Document 1 JP-A-9-192584 Patent Document 2 JP-A-57-7510 Patent Document 3 JP-A-07-80399 Patent Document 4 JP-A-200-1121068 Figs. 29 and 30 are diagrams for explaining the roller-type coating device, and Fig. 29 is a perspective view showing a roller-type coating device,? Fig. 30 is an exploded perspective view showing the roller type coating device. In Figs. 29 and 30, the reference number 80 is an & coating device type roller. The roller-type coating device is usually made from a roller brush 82, a roller support 85, and a handle 88. The roller brush 82 is wound on a coating surface of a carriage, which will be a coating surface, and applies a material on the coating film surface. . A roller support 85 rotatably supports the roller brush 82, and a handle 88 supports it and feeds a coating material towards the roller brush 82. The handle 88 includes a holding part 88a held by a worker and a lever operation 88b. A body-4-structure 86, crank-shaped, engages the front end of the holding part 88a. The body structure 86 is a coating of coating material made of a rigid metal material, such as stainless steel. A coating material feeding tube is coupled to the rear end of the holding part 88a of the crank 88. The coating material feeding tube is flexible such that the work holds the holding part 88a and continues the coating work while moving. The operation lever 88b allows and interrupts the feeding of a material of *; Pressurized liner of the coating material feeding tube towards the structure body 86. A diffuser 83 is mounted in a radiative manner on the rod support 85. The diffuser 83, as shown in FIG. 30, includes a plurality of diffuser units 831 to 836. The units of duster 831 to 836 take each polygonal column having a star-shaped cross-section, which includes an empty part having a cross-section in shape of star that expands radially from the center towards the respective vertices, and a cavity in the center of each of the peripheral areas each between the vertices. The units of the diffuser 831 through 836 are successfully positioned so that the upper end of the empty part of each diffuser unit 831 to the diffuser unit 836 is commu nicated with the cavity pawls of the n umber units. d ifusor 831 to 836 - 5 - adjacent to the former, and the reserve chambers of the facing material are defined by the peripheral parts of the diffuser units 831 to 836 and the inner peripheral surface of the roller brush 82. The roller brush 82 covers the diffuser 83. The roller brush 82 includes a cylindrical rod 82a from which both ends (as seen in the axial direction) open, and a cylindrical brush element 82b applied to the outer periphery of this roller. The exit holes are formed in the roller 82a, while they are placed on the entire periphery of the roller, each orifice communicatingly interconnecting the inner side and p the outer side of the roller 82a over the entire periphery. The roll-type coating device 80 constructed in this manner is used in the following manner. The clamped worker, the clamping part 88a of the handle 88 by hand, and brings the brush for rollers 82 in contact with the cladding surface, and operates the operating lever 88b. A coating material is pressurized into the containers of coating material in the diffuser 83 in the manner of a path of the holding part 88a, the structure body 86, the roller support 85, and the coating material fed to the plates. holes of a roller shaft 81. The coating material is introduced in a dispersed manner into the reserve chambers of the coating material defined by the peripheral portions of the diffuser units 831 to 836 and the peripheral surface of the roller brush 82 through openings each between the upper ends of the brush. the empty part of each unit of - 6 - diffuser 831 to 836 and the cavity part of each diffuser unit 831 to 836. The coating material that is diespersely introduced into the reserve chambers of the coating material is twisted towards the outer periphery of the roller 82a through the outlet holes, and it infiltrates the brush element 82b. In a state in which the coating material has sufficiently infiltrated the brush element 82b of the roller brush 82, the worker presses the roller brush 82 against the coating film surface, and enlists the brush for rod 82 on the coating film surface, such that the material lining which has permeated in the brush element 82b-is applied to the coating film surface. The roll-type coating device 80 has the following advantages. In the coating operation, the brush for the rollers 82 is wound in an unrestricted manner on the coating surface, so long as it does not slip, despite the fact that its construction is simple and a viscosity of the coating material is high. In addition, the roller brush 82 rotates without any interruption. The coating material can be uniformly coated. There is no loss of the coating material between the mounting part and the sliding part. There is no opportunity for the liner material to fall out of the roll-like coating device 80 and, consequently, the material is adhered to the carriage body, and the work environment deteriorates. The reduction of the production of a coating material is avoided. - 7 - The inventor (s) found that the aforementioned roller-type coating device still includes the following problems. 1) In order to uniformly apply a coating material on the coating film surface, it is always necessary to infiltrate a sufficient quantity of a coating material into the empty star-like part and the reserve chambers of the coating material. According to the above, after the coating work is finished, a considerable amount of coating material is left in the diffuser 83. EW coating material wears, and the coating material:; it flows out from there to possibly soil the surrounding. To wash the dirt, a lot of work is needed. 2) In the roller-type coating device, the roller shaft 81 is passed through the axial center of the cylinder. According to the above, the number of parts is large, and it is required.-, much labor to wash the roller shaft 81. 3) Furthermore, in the roller-type coating device, a coating material is fed to the roller of only one end thereof, and thereafter the sufficiently pressurized coating material does not reach the front end thereof. Accordingly, it is difficult to uniformly apply the coating material to the complete roller. 4) And, in the roller-type coating device, only one end of the roller is supported in a cantilever shape. - 8 - To apply a force uniformly on the complete roller, experience is required. According to the above, the roll-type coating device is not easy to handle by man. In the case of a coating film formed by the use of the roller-type coating device, a difference in a film thickness is greater between both ends of the roller part. Therefore, it can not ensure a sufficient film thickness. For this reason, it is necessary to apply the coating to the coated surface which has insufficient thickness. Nevertheless,. it is difficult to ensure a uniform coating for the coating. The roller type coating device of the type in which a coating material is pressurized to the roller at both ends of the roller and the roller is supported at both ends, is known as described in Patent Document 2. FIG. 31 is a plan view showing the roller-type coating device (the roller is illustrated by a phantom line). In the figure, the reference number 101 is a tube for feeding coating material; 1 02 is a roller body, 1 03 is a roller core; 1 04 is a port for unloading coating material; 1 05 is an empty L-type gasket; 106 is a relay tube; 1 07 is a ball; 1 08 is a material-coating / handle feeding tube; and 109 is a division plate. A coating material coming through the material-coating / handle feeding tube 108 branches to the right and to the left of the relay tubes 1 06. The -9-coating material enters the material feeding tube. of coating 101 by means of the empty L-type joint 105, and flowing out of the coating material discharge port 1 04 and flowing through the roller core 1 03 towards the roller body 102. And it is uniformly applied to an object that will be coated. The roller-type coating device is especially effective when it is used for a case where in the coating of a vertical wall or the like, the roller body 102 is vertically raised and rolled parallel to the floor. In this case, the balls 1 07 close the inlet of the lower relay tube 106 ... According to the above, the coating material flows into the coating material feed tube 1 01 only from the lower relay tube 106; reaches partition plate 109; flows from the partition plate 1 09 and flows out of the roller through the discharge port of the upper coating material 104. Coating material is not supplied from the relay tube 1 06. The coating material flows to the side lower of the roller body 106 by gravity. Therefore, even if the coating is carried in a state in which the roller body 1 02 is raised vertically, the coating material can be uniformly applied to the object to be coated. The roll-type coating device still includes the following problems to be solved. 1) In the document, the core of rodil 1 03 is not discussed in detail. Then, the roll core 10 will be estimated to include a number of known steps or a structure similar to a sponge. If so, a considerable amount of coating material will remain inside the roller. In accordance with the foregoing, the technique under discussion includes the same problem as the roll-type coating device described in Patent Document 1. 2) In the roller-type coating device, the coating material feed tube 1 01 is passed through the axial center of the cylinder. According to the above, the technique under discussion includes the same problem as that of? roller type coating device described in Patent Document 1. 3) In this roller-type coating device, the partition plate 109 is provided in the center. The coating material is pressurized in the roller from both ends of the roller. Even if a pressure difference occurs between the coating materials on both sides of the partition plate 1 09, the pressure difference is not removed since the partition plate 109 is presented. As a result, the thicknesses of the resulting coatings formed by the coating materials fed from both sides of the partition plate 109 are different from each other. In addition, due to the presence of the partition plate 109, the same phenomenon is that in the case where the coating material is fed from only one end of the roller, it occurs. The coating material having a sufficient pressure fails to reach the partition plate located in the deep part of the coating material feed tube 101, and it is difficult to uniformly coat the object to be coated. In this way, the aforementioned problems can not be solved by the roller-type coating device described in Patent Document 2 in which the coating material is fed to the roller from both ends of the roller and the roller is supported at both ends of the roller. same. None of those conventional roller-type coating devices including the last mentioned device are non-automatic. Even if the surface to be coated is flat, the surface is manually coated when using the roller. That is, the coating process is not automatic. When the roll coating device is applied to the coating of an object to be coated from which the surface to be coated is curved, it is difficult to apply the roller brush uniformly on the curved surface. According to the above, it is considered that it is more difficult to automate such coating work. The spray coating process is used exclusively for the automatic coating of the coating material. In the spray coating process, the coating material sprayed from the nozzle becomes powder around a pattern of coating material. Therefore, the uniform coating is impossible. The coating film formed by the powder part is manually descorteza, and the work of descortezamiento needs considerably problematic work. In this way, the spray type automatic coating apparatus has been used practically, but it is still unsatisfactory in its operations. For prior reasons, a first object of the present invention is to reduce an expense of coating material and distribute the coating material uniformly to the roller brush. The invention provides a pressure fed coating roll, and a roll coating device which is capable of coating the coating material uniformly coating a coated surface having a curved surface, when using the pressure fed coating roll, viz. . , a roller coating device that is effectively operable for coating a curved surface. In addition, the invention provides an automatic roller coating device that is capable of evenly coating a surface to be coated as a curved surface with the coating material when using the curved surface operable roller coating device. To achieve a uniform finish quality of the coating, which is free of individual workers' difference, it is necessary to automate the coating process when using the coating robot. The known and conventional roller coating device (coating rollers fed 1 - under pressure from one or both ends) is not suitable for the automatic coating process and from then on, it is not automatic. Even in the case of coating the flat surface, the worker manually coats that surface with the coating material when using the roller. That is, the coating process is not automatic. When the roller coating device is applied to the coating of an object to be coated, of which the coating surface is a curved surface, it is easy to apply the brush to roll them one on the curved surface. In accordance with the above, it is considered that it is more difficult to automate such coating process. A second invention is made to solve the above problem, and has a second object for imaging the wear of the coating material and to provide an automatic coating apparatus which 1) uses the pressure-coated coating of a end or both ends (referred to as "coating the pressure die") according to the first invention, which is capable of uniformly distributing the coating material to the brush for rod, 2) feeds the coating material the removal of the powder material from the coating material, and the removal of the powder material from the coating material, and the storage of a coating material for the coating material for a coating tank, by agitating the coating material in the tank. then 3) feeds the most suitable amount of the coating material towards the pressure-fed coating roller in the-14-coating cabinet, and 4) causes the The robot device according to the first invention automatically executes a roll-based coating process for automatically and evenly coating a curved coated surface with the coating material. The objects to be coated were currently coated with the coating material when using the automatic coating device according to the second invention. The result is that the lining of the curved components of the automobile such as roof, roof, trunk, bumper, fender, or door; It was; Excellent. It was found that in the coating by the automatic coating apparatus, a problem to be solved arises. That is, when a rectangular area is coated, a film of; coating on a peripheral edge of the rectangular area is thicker than the remaining part. To solve the problem, a third invention is directed to solving the problem, and has a third object to provide a coating method which is capable of making a thickness of a coating film on the uniform square area over its entire area when using the automatic coating device.

With such construction, according to the invention defined in claim 1, a volume occupied by a coating material in an area of the solid cylindrical body is reduced. There is no need for the roller shaft, which is required in the conventional coating device. The remaining coating material after the coating work is finished is small in quantity, a wear of coating material is small, maintenance of the coating device is easy, and the number of component parts is reduced. In addition, the pressure-fed coating roller is operated in an adaptive manner by a locally curved surface. According to the above, the curved surface can be coated excellently. In a pressure-fed coating roll defined in claim 3, which depends on claim 1 or 2, a groove extending in the circumferential direction, which is connected to the outlets of the radial holes, is formed in a surface of the solid cylindrical body. With such a feature, the coating material flowing out of the radial holes spreads rapidly in the circumferential direction along the circumferential groove. As a result, the coating material is spread over the entire surface of the roll to thereby ensure a uniform coating. - 1 7 - A roller coating device defined in claim 4, which depends on claim 1 or 2, comprising: a pressure-fed coating roller defined by any of claims 1 to 3; the press feeding tubes of coating material connected at both ends of the axial central bore of the solid indian body of the pressure roller; and an arm portion for supporting the pressurized coating roller at both ends of the coating roller supplied under pressure. With this characteristic, the coating material is supplied from both ends of the roller towards the roller, and it is supported-at both ends. A liquid pressure is uniform over the axial center hole passing through the axial center. A pressure force applied to the pressure-fed coating roller is uniform, so that the coating material is distributed over the entire roller. A curved surface operable roller coating device defined in claim 5, comprising: a pressure fed coating roller; press feeding tubes of coating material for pressurizing the inside of the coating roller supplied under pressure from both ends of the coating roller supplied under pressure; an arm portion for supporting the coating roller supplied under pressure at both ends of the coating roller supplied with pressure; a rotary support mechanism for supporting the arm portion of the arm such that the arm is rotatable in a plane parallel to a vertical surface including the shaft of the pressure roller; and a vertically movable support mechanism for supporting the arm part such that the arm part is vertically movable. With such construction, the support moves the roller brush in accordance with a coated surface. The resulting coating is free of spots.

In a curved surface operable roller coating device defined in claim 6, the pressure fed coating roller defined in claim 5 is. the pressure-fed coating roller defined by any one of claims 1 to 3. When the curved surface operable roller coating device defined in claim 5 is used, the arm part is rotated in a vertical plane including an axis of the roller and it is vertically mobile. Although any special limitation by one type of pressurized coating roller used deteriorates, such a construction reduces the amount of remaining coating material, and eliminates a wear of coating material. Maintenance is easy, and the coating material is spread over the entire roller surface. Thus, the thickness uniformity of the coating is improved, and a favorable use handling is ensured. An automatic coating apparatus of the roller type defined in claim 7 comprising: a three-dimensional moving robot that is movable in three dimensional directions, the curved surface operable roller coating device defined in claim 5 or 6 joining to the tip of the robot's arms; a robot control unit to control the three-dimensional moving robot; a pump control unit for controlling a flow rate of a coating material to be pressurized to the roller coating device, operable by curved surface. With such construction, the operation of the robot (the number of, roller brush revolutions, pressure force), the amount of coating material fed, the liquid feed pressure and the like can be automatically set allowing for the viscosity of the coating material, environments of the coating material (temperature, humidity, etc.) and the like.

By convention, it is difficult to spray a high viscosity coating material, such as the aqueous coating material to coat the film protection. This hinders the automation of the coating process using such de-coating material. For this reason, the coating using the aqueous coating material is made manually using the roller. To automate the coating process by the roller, it is difficult to adapt the roller to a curved surface. This makes it impossible; automate the coating process.

Fig. 1 is a perspective view conceptually showing a coating device including a pressure fed coating roller, which is a first embodiment of a first invention. In Fig. 1, the coating roller pressurized according to the first embodiment of the invention is a part of a roller brush installation 10. The coating roller pressurized according to the first embodiment of the invention it will be described first. Fig. 2 is a longitudinal sectional view showing the roller brush installation when viewed in the axial direction. Fig. 3 is a cross-sectional view taken on the line A-A in Fig. 2. The roller brush installation 10, as shown in Figs. 2 and 3, includes a solid cylindrical body 1 1 and a - 42 - roller brush 12 applied to the outer periphery of the solid cylindrical body 1 1 in an adjustment manner. The solid cylindrical body 1 1 is made of synthetic resin, metal or the like, and is solid. It has a solid structure in which a feeding passage of coating material is formed only with an axial central hole 13 which passes through the axial center of the solid indic cylinder body., and the radial holes 14 extending radially from a plurality of positions of the axial central hole 1 3. As shown in Fig. 3, a total of four radial holes 14 are formed, which extend radially from the hole axial center 1 3 while they are angularly separated from each other by 90 °. In the modality, four radial holes 14 are used; however, the number of radial holes is not limited to four, as a matter of course. That the number of radial holes 14 is not large, is one of the characteristics of the invention. The reason for this continues. If the number of radial holes is large, a large amount of coating material remains in the radial holes. According to the foregoing, the roller of the invention does not differ from the conventional roller in which a large amount of coating material remains, in the beneficial and operative effects. Specifically, about 2 to 8 radial holes are preferred as shown in Figs. 4 (a) to 4 (f). If the number of radial holes is increased in excess of those - 43 - just mentioned numbers, the beneficial and operative effects produced by the resulting roll resemble the conventional roller as shown in Fig. 4 (g). Such should be avoided. A diameter of each radial hole is determined depending on a viscosity of a coating material used. Further, in the first embodiment, the slits 15 (see Fig. 5) are formed at the outlets of the radial holes 14, each slit extending around the solid cylindrical body. With the provision of the slits, the flowing coating material? -from the radial holes are easy to spray in the circumferential direction while being guided by the circumferentially extending slits. According to the foregoing, the coating material spreads uniformly and rapidly over the entire roller surface to contribute in this way to the formation of a uniform coating. A flange 16 is formed at one end of the solid cylindrical body 11, and a nut 17 is formed at the center of the other end thereof. The roller brush 1 2 includes a cylinder 1 8 made of a rigid material, such as synthetic resin or metal. The fibers made of synthetic resin are joined or planted in the cylinder 18. A number of holes 1 9, which are located in the slits 1 5, are formed in the cylinder 18, while they are passed through the latter. The installation of roller brush 1 0 is installed in the following manner. The roller brush 12 fits into the solid cylindrical body 1 1 from the other end thereof a state in which the cover 20 joins the flange 1 6 of the solid cylindrical body 1 1. Then, a disc 22 engages with the other end of the solid cylindrical body 1 1 with a cover 21 interposed therebetween. A pin 23 is screwed into a nut 1 7 of the solid cylindrical body. Fig. 5 is an exploded perspective view showing the roller brush installation 10 shown in Fig. 1. The roller brush installation 10 includes the solid cylindrical body 1 1 and the roller brush 12. It is installed in such a way that the disc 22 engages with the end of the roller brush 12, and the pin 23 is screwed into the solid cylindrical body 1 1 (the installation process will be described later). As illustrated, the radial holes 14 radially extend from the axial central hole 13, and the slits 15 extend from the outlets of the radial holes 14 in the circumferential direction to produce something round of the solid cylindrical body.

SEC A MODAL D AID OF THE INVENTION A second embodiment of the invention will be described. The second embodiment relates to a way of feeding a coating material to the axial central hole 13 of the solid cylindrical body 1 1 including the pressure feed roller 45, and a way to support the solid cylindrical body 11. As described in connection with Fig. 29, in the conventional roller coating device, the coating material is fed to the roller from one end of the roller, and the roller is supported in a crank shape. According to the above, the conventional roller coating device suffers from the disadvantages as mentioned above. In the present embodiment, the cladding material feed tubes 24 (See Fig. 1) are connected to both ends of the axial central hole 13 of the solid cylindrical body 11. The pressure-fed coating roller is supported in a rotatable manner at both ends by the arms 31, and the arms 31 are coupled together by a lower structure 32, whereby a support 30 is formed. The coating material feed tubes 24 are coupled to both ends of the solid indium body 1 1, and the ends of the coating material supply tubes 24 are connected to a pump (see reference number 73). in Fig. 11). The roller brush installation 10 constructed in this manner receives the coating material from both ends of the axial central hole. The coating material supplied to the axial central hole 1 3 is fed into the annular grooves 1 5 in the manner of the radial holes 14, and is distributed through the slits to the radial holes 14.

- A known structure can be used for such a structure that the roller brush installation 10 is rotatably supported by the arms 31, and the coating supply press tube 24 is connected to the axial central hole 13 of the cylindrical body. solid 1 1. Thus, in the current embodiment, the coating material is supplied to both ends of the pressure-fed coating roll, and the pressure-fed coating roll is supported at both ends thereof. Therefore, a liquid pressure is uniform over the axial axial hole passing through the axial center of the roller. In addition, a depression force applied to the pressure-fed coating roller is uniform. As a result, the coating material is evenly distributed to the complete roller.

THIRD MODALITY OF THE INVENTION A third embodiment of the invention will be described. A coating device of the third embodiment, as shown in Fig. 1, includes a rotary support mechanism 40 for rotating the support 30 that supports the roller brush installation 10 in a direction of an arrow A, and a mechanism vertically movable support 50 for vertically moving the same in a direction of an arrow B. The support 30 includes the two arms 31 and the lower structure 32 is bridged between those arms. The two arms 31-47 - rotatably supports the roller brush installation 10 between them. The support 30 is mounted to the rotary support mechanism 40, and the rotary support mechanism 40 is mounted to the vertically movable support mechanism 50. The rotary support mechanism 40 is constructed such that a plate 41 extends over the upper surface of the lower structure 32 in parallel with the axis of the roller brush installation 10. The plate is rotatably coupled to the intermediate structure 33 by means of a bolt 42. FIG. 6 is a diagram for explaining the operation of a rotary support mechanism 40 in FIG. 5: Fig. 5 (a) shows a state in which the roller is rolled on a flat surface; Fig. 68b) shows a state in which the roller is wound on a curved surface upwards to the right; and Fig. 6 (c) shows a state in which the roller is wound on a curved surface down to the left. In Fig. 6 (a), the roller brush installation 10 is wound on a flat surface, and from there, the intermediate structure 33 takes a horizontal posture around the pin 42. In Fig. 6 (b), when the roller brush installation 10 moves towards a curved surface upwards to the right, the intermediate structure 33 is rotated around the bolt 42. According to the above, while the intermediate structure 33 maintains the horizontal posture, the installation of Roller brush 10 located underneath it is left to wind on and along the - 48 - surface curved upwards to the right. In Fig. 6 (c), when the roller brush installation 10 moves to the curved surface upward to the left, the intermediate structure 33 is rotated about the bolt 42 in the direction opposite to the direction in Fig. 6. 6 (b). According to the foregoing, while the intermediate structure 33 maintains a horizontal posture, the roller brush installation 10 under it can be wound on and along the surface curved upwards to the left. A part of the press feeding tube of facing material 24 is made of a flexible material, and its length is sufficiently long. Therefore, even if the roller brush installation 10 is rotated, the press feeding tube of coating material can follow a movement of the. roller brush installation 10. In the third embodiment, the support 30 further includes the vertically movable support mechanism 50. FIG. 7 shows the vertically movable support mechanism 50. In FIG. 7, in the vertically movable support mechanism 50, two arms 51 that fully support the upper structure 34 at the free end are supported on a board 33a of the intermediate structure 33. by means of a bolt 52. Those arms 51 are pushed upwards by a spring (a compression spring screwed in this case) 53. The vertically movable support mechanism 50 includes - 49 - an adjusting screw 54 for adjusting a force of spring thrust 53, and the screw is spliced onto one end of the spring 53. In the vertically movable support mechanism 50, a maximum opening angle of the arms 51 is set to be within approximately 20 ° to 60 ° for a angle regulating means (not shown). Our experiment showed that the angle range of approximately 20 ° to 60 ° allows a natural vertical movement of the support 30. It is preferable that the arms 31 that rotatably support both ends of the brush installation, rollers 10 are tilted at an angle within of a range of approximately 20 ° to 60 ° with respect to the horizontal plane. This fact was also found by our experiment. A weight applied to the roller is preferably within a range of 0.6 to 1.5 kgf (5.7 to 14.7 N). If the pressing force is smaller than any value of the range of forces, a rolling operation of the roller deteriorates, an inclination of a configuration based on the curved surface deteriorates. Conversely, if the pressure force is greater than any value of the range of forces, the surface to be coated (car body in the case of the automotive lining) is deformed, an (illegible) roller deteriorates, and a thickness Film from the coating surface increases at both ends of the roller. The weight applied to the roller can be increased by adjusting the adjusting screw 54 to increase the opening angle.

It is evident that the vertically movable support mechanism 50 can be replaced by any other suitable mechanism, such as a pantograph mechanism. Fig. 8 is a diagram for explaining the operations of the vertically movable support mechanism 50 of Fig. 7: Fig. 8 (a) shows a state in which the roller is wound on a lower surface; and Fig. 8 (b) shows a state in which the roller is wound on a high surface. In Fig. 8 (a), the roller brush installation 10 is wound on a low surface. According to the above, in the vertically movable support mechanism 50, the opening angle of the arms 51 increases to allow the roller brush installation 10 to move downwardly from the lower surface. In Fig. 8 (b), the roller brush installation 10 is wound on a high surface, in the vertically movable support mechanism 50, the opening angle of the arms 51 is reduced to allow the brush installation for 10 rollers retract to the high surface. In this way, the third embodiment includes the rotary support mechanism 40 for rotating the support 30 in the direction of an arrow A in FIG. 1, and the vertically movable support mechanism 50 for vertically moving the same in the direction of an arrow B. Therefore, the roller brush installation 10 is always pressed against a curved surface having slopes vertically and horizontally inclined, from the right-anterior-51. Fig. 9 is a diagram showing a roller that is effectively operable for the coating of a curved surface and a modification of the roller brush installation of Fig. 2: Fig. 9 (a) is a cross-sectional view showing the coating a flat surface, and Fig. 9 (b) is a cross-sectional view showing the coating of an irregular surface. Fig. 10 is a diagram showing an outward appearance of a roller brush installation including five divided rolls: Fig. 10 (a) is a view showing the roller brush installation; when it is in a normal state; Fig. 1 0 (b) is a view showing the installation of a roller brush when the divided rollers separate; and Fig. 10 (c) is a partially elongated view showing the roller brush installation of Fig. 6 (b). As shown in Fig. 9, the roller brush installation 60 is made up of a plurality of split rolls 60a including a solid cylindrical body 61 and a roller brush 62 is fitted to the solid cylindrical body 61, a tension spring 61b to provide forces of thrust to the adjacent split rollers 60a, and a flexible tube passing through the central axial holes of the adjacent split rollers located 60a. The divided solid cylindrical body 61 is made of synthetic resin, metal or the like, and solid. The cylindrical body -52 divided solid 61 has a solid structure including the lining material feed passages formed by an axial central hole 63 that passes through the axial center thereof, and the radial holes 64 extend radially from a plurality of positions of the axial central hole 63. The annular cavities 61 a are provided on both lateral surfaces. The tension springs 61 b are joined to the annular cavities 61 a, such that the adjacent split rollers 60 a are mutually pulled. As seen from an elongated view of FIG. 10 (c), those divided rollers 60a can be separated from each other by applying external forces themselves. The radial holes 64 are a total of four holes extending radially from the axial central hole 63 while they are angularly spaced by 90 °. The number of radial holes is not limited to four, and the diameter of each radial hole can be selected, as desired, depending on the factors, such as a viscosity of the coating material, as a course material. A single flexible Teflon tube 65 passes through those axial center holes 63 and the tension springs 61 b. Within the axial center holes 63, the Teflon tube 65 is placed in the axial center holes 63 in a close contact manner such that the holes formed in the Teflon tube 65 are placed in the radial holes 64 that extend from axial center holes 63.

When constructed in this way, the coating material is fed uniformly to the radial holes 64 of the divided rollers 60a, and the tension springs 61b are not stained with the coating material. In addition, in the embodiment, the slits are formed in the outlets of the radial holes 64, each slit extending around the solid cylindrical body. With the provision of the slits, the coating material flowing from the radial holes are easy to spray in the circumferential direction while being guided by the extending slits, circumferentially. Accordingly, the coating material spreads rapidly and uniformly over the entire roller surface to contribute in this way to the formation of a uniform coating. A flange 66a is formed on the outer periphery of the outermost solid split cylindrical body 61, and a disk 66 having a nut 66b is formed on the inner periphery of the divided solid cylindrical body 61. The roller brush 62 includes a cylinder 68 made of a rigid material, such as synthetic resin or metal. The fibers made of synthetic resin are joined or planted in the cylinder 6. A number of holes, which are located in the slits, are formed in the cylinder 6, while passing through the latter. The brush installation for rollers 60 is installed in the following manner. The roller brush 62 fits in the solid-solid-cylindrical body 61 from the other end thereof in a state in which a cover 61 c is attached to the flange 66 a of the solid cylindrical divided body 61. Then, a disc 66 meshes with the other end of the solid cylindrical body divided into 61 with a cover 61 c interposed therebetween. A bolt 69 is screwed into a nut 66b of the divided solid cylindrical body 61. To coat a flat surface, as shown in Figs. 9 and 10 (a), the split rollers 60a are rotated while aligning with an axial line and the coating material is fed to the roller from both ends thereof. This case is the same as that in Fig. 2. To coat the uneven surface, the divided rollers 60a, as shown in Fig. 9 (b), are exchanged with each other along a regulating surface, while resisting a frictional force perpendicular to a force Tension of the tension springs 61 b, and by the flexible Teflon tube 65. Therefore, the lining material is coated on the irregular surface. If the roller brush installation 60 of the splitting type is applied, instead of the brush installation for rollers 10, to the second and third modes, the resultant beneficial effects are further increased, as a matter course.

FOURTH MODALI DAD OF THE I NVENTIO N A fourth embodiment of the invention will be described with reference to Figs. 1 1 and 12. The fourth embodiment refers to a - 55 - automatic coating, and in the automatic coating, the roller coating device operable by curved surface according to the third embodiment joins the tip of a robot arm . Fig. 1 1 is a diagram showing an automatic coating apparatus which is a fourth embodiment of the invention. Fig. 12 is a block diagram showing a central control unit in Fig. 1 1. In Fig. 11, the reference number 70 is an automatic coating apparatus; 71 is a coating robot; 72 is a surface-curved operable roller coating device attached to the tip of a moving part of the coating robot 71; 73 is a pressure-fed pump of coating material; 731 is a pump control unit; and 74 is a robot body, which is a multi-articulated robot of the teaching synchronization type. The robot body 74 includes a mobile part 741 operatively coupled, and its robot operation is controlled by a robot control unit 742. The robot control unit 742 receives a control command from the central control unit 75, and controls the robot operation of the robot body 74. The reference number 76 is a temperature sensor for sensitizing the temperature in a coating environment, and 77 is a humidity sensor 77 for sensitizing moisture in a coating environment. The temperature sensor 76 and the humidity sensor 77 send sensitization signals to a central control unit 75. In Fig. 12, the central control unit 75 is made of CPU 50 to process the temperature data. humidity received, decoding the data in the RAM, and controlling a global system of the automatic coating apparatus, such as a pump control and robot control, a RAM 751 for storing data about ambient temperature and humidity, type and viscosity of a coating material, pressure of the pressure-fed coating pump, pressure of the coating material, and others, a ROM 752 for storing the operating procedures in the CPU 750, a display device 753 for displaying the state of the current operation, the values entered by the board, and others, a board 754 to enter and change the data, and an interface 755 to transmit and receive signals to and from the devices and xternos. Examples of external devices are the temperature sensor 76 for sensitizing the temperature in a coating environment, the humidity sensor 77 for sensitizing the moisture in a coating environment, the pump control unit 731 and the robot control unit 742. Next, the operations of the automatic coating apparatus 70 will be described. An operator enters the coating conditions (eg, a type of coating material to be used to coat an object to be coated and a thickness of a coating film to be formed on the object) by the use of the board. The sensitization signals derived from the temperature sensor 76 the humidity sensor 77 are sent to the central control unit 75. The central control unit 75 receives the coating conditions and the sensitization signals from the sensors, and computerizes, to satisfy the coating conditions, an optimum amount of the coating material discharged from the pump, and the optimum pressure and speed of movement of the coating roller pressurized in accordance therewith, and as a result it sends the control commands to the coating unit. pump control 731 and-the moving part 741. In accordance with the control commands, the pump control unit 731 controls the pressure fed coating pump 73 to adjust a quantity of coating material to be pressurized, and the moving part 741 controls the robot body 74 to adjust the force of pressure and the speed of movement for the roller. The coating material supplied to a pressurized coating roll surface is moved downwardly from a lower part of the coating roll fed by gravity pressure, when a viscosity value of the coating material falls within a range of some values of viscosity. In order to compete with this, it is preferable to reciprocally, several times, move the pressure-fed coating roller over another contact surface before the coating process begins, to evenly distribute the coating material attached to the lower part of the coating. roll to the surface of full roller. In so doing, the moving part 741 of the robot body 74 moves, and thereafter, the curved surface operable roller coating device 72 attached to the tip of the movable part also moves. At this time, even if the coating surface is irregular, the curved surface operable roller coating device 72 of the invention follows, in motion, an irregular surface variation of the uneven surface, thereby gaining a coating film of uniform thickness. As described above, the present embodiment can produce a coating film that is much more uniform in thickness than by the conventional automatic spray type coating device. Only a part of the surface of the coated object on which the roller has been rolled is coated. Therefore, there is no opportunity for the powder to be formed as in the conventional spray-type coating device. In addition, there is no need for the robot body 74 checks an irregularity on the coated surface each time the coating is carried out, and moves the moving part 741 vertically along an irregular surface variation of the uneven surface. It is sufficient that the rod moves merely in the horizontal direction. According to the above, the control is considerably simplified. This is an advantageous feature. The same thing is true for a case where a surface to be coated has an inclined inclination in horizontal directions. According to the above, it is sufficient to move the roller in the horizontal direction, and thereafter, the control is greatly simplified. As described above, according to the present invention, there is no need for manual coating work using the roller. According to the foregoing, the coating material is uniformly applied to the entire roller, and from then on, there is no uniformity of the coating film thickness. There is no need to repeat such a process that the coating material is applied to the roller several times, and then the coating material again infiltrates the roller. This advantageously results in the reduction of the labor cost and working hours, and the coating booth. In addition, the roller-type automatic coating apparatus according to the present invention can be applied to the coated objects that have been coated by the use of the roller, without any limitation. Specific examples of those objects are objects concerning vehicles and construction, ships, furniture, and objects concerning roads. In a case where the vehicle object is the car body, the invention can be applied not only to the roof, roof and trunk, but also vertically to the installed components - 60 - such as bumpers, fenders, and doors, when using the material protector or anti-tear material. The coating material used by the invention is not limited to the coating material that is conventionally used by the known roller coating process, but can be an aqueous coating material, an organic solvent coating material and the like. The embodiments of the second invention will be described with reference to the related drawings. The pre-stages of the formation of a protective film to protect a coating film of an automobile is as follows: 1) Cleaning a car by washing water; 2) drain the washing water; 3) masking the carriage body except a part thereof on which a protective film will be formed; 4) coating a protective film; 5) perform a correction and finishing coating if necessary; and 6) drying the coated carriage. If a car surface is not stained, steps 1) to 3) may be omitted. 1) A car W on which a protective film is formed undergoes a washing step. In the stage, the carriage body is completely washed by a tub washing machine of the tub type using a rotating brush, in order to remove the rainwater, the dust and the adhesion similar to the surface of the film. coating. In the cold season, water droplets attached to the surface of the coating film freeze - possibly to damage the surface of the coating film. To avoid this, lukewarm water of 30 to 50 ° C is used for washing. 2) In the step of draining washing water following the washing step, the washing water left on the surface of the coating film of the automobile W, which is washed in the washing step, is removed when blowing the hot air of approximately 30 to 70 ° C on the surface of coating film. The warm water used in the washing step and the hot air used in the washing water drain stage make the coating of an aqueous coating material good, which is carried out in a coating stage as a post stage. Therefore, a surface temperature of the automobile is suitably maintained. The surface temperature of the automobile is 1 5 ° C or more, preferably 20 to 30 ° C in consideration of the formability of the film of the coating material. 3) In the next masking step, to mark the boundary between a coating area to be coated with an aqueous coating material and a non-coating area, a tape is applied to the surface of the automobile W having the wash water drained and dried in the washing water drain stage. The open intake duct in the engine cover, and non-lining parts, e.g., resin parts, located within the lining area, are covered with a cover or the like. 4) In the coating stage, the coating area defined by the tape in the masking step is - 62 - coated with an aqueous coating material mainly containing acrylate emulsion (eg, "Wrap Guard L", made by Kansai Paint Corporation) when using the roller brush coating device according to the second invention. 5) In the next stage of finishing coating, which can be carried out if necessary, the tape applied in the masking step is debarked, and the cover is removed. In a finishing coating, the small uncoated portions in the coating area are manually coated with an aqueous coating material by using a brush or a small roller brush. The masking step, the coating step, and the finishing coating step are carried out inside the coating booth. 6) In the subsequent drying step, the coated carriage is placed in an IR drying oven, and irradiated with infrared rays for approximately 30 to 90 seconds, thereby improving the drying of the coated aqueous coating material including the inside of the same. Accordingly, the aqueous coating material is dried by uniformly heating the entire coated carriage body when using a hot air drying oven or by using only the hot air drying oven, thereby forming a protective film. Where the hot air drying oven is used, it is preferred to dry the coating material for approximately 21.0 minutes under conditions such that a drying temperature of 50 to 1000 ° C and a hot air speed is 0.5. at 8 m / sec, to ensure satisfactory film formability of the aqueous coating material and to protect the bonded components such as various types of electrical components. The aforementioned steps can be replaced by online stages. In this case, after the coating stage (intermediate coating and finishing) of the automobile ends and an inspection stage ends, the car body is coated with the protective coating material, and dried, and from there the components such as the meters are attached to the car, through which a finished car is presented. The "coating material" used herein is a coating material for forming a coating film to protect the coating of the carriage body. A viscosity of the coating material is higher than that of the normal color coating material. Accordingly, it is difficult to make such a coating for the formation of the protective film by using a conventional spray-type automatic coating apparatus. For this reason, the manual work that uses the coating roller is used for the coating. The automatic coating roll according to the first invention allows the steps of forming a high viscosity protective film to be automated. - 64 - FIRST MODALITY OF THE SECOND INVENTION Fig. 1 3 is a diagram showing a positioning of an automatic coating apparatus which is a first embodiment of a second invention. Complete automation of the coating stage 4) of those steps 1) to 6) is illustrated in Fig. 1 3. In Fig. 13, a chamber that prepares the coating material 1 00 contains a coating material feeding system 1 10 for supplying a coating material to the coating roller and a detergent feeding system 160 for feeding a detergent to the coating roller for clean the coating roller; The coating material feed system 10 will be described first.

An aqueous coating material for the forming film contained in the coating material mold 11 11 is sucked by the pump 12; it comes out of the mold of lining material 111; its pressure is controlled by the regulator 113; and the impurity contained herein is filtered through the solution filter 114; and enters the coating material tank 115. The regulator 120, the scale checker 120A, the solution filter 121 for filtering the foreign matters mixed in the coating material, a heat exchanger 130 for adjusting the temperature of the coating material which is transported, and a liquid quantity stabilizer 140 are located outside the coating material preparation chamber 100. The coating material flowing out of the liquid quantity stabilizer 140 branches to two pipes 151 and 152 to feed the material of coating to a second automatic coating apparatus in a coating booth. After the coating material passes through the two automatic coating apparatuses, the remaining coating material passes through a return pipe 155 and returns to the coating material tank 115. The detergent feeding system 160 now it will be described. The reference number 161 is a cylinder of detergent; 162 is a pump; 162A is a pump drive motor; and a detergent filter 163 is a detergent filter. A detergent flowing out of the detergent filter 163 branches to two pipes 153 and 154, and is fed to the two automatic coating apparatuses within the coating cabinet. - 66 - Reference number 170 is a coating booth. Two coating robots 171 and 1 72 are provided in the coating booth 170. Reference numerals 171 a and 172a indicate the pressurized coating rollers of both ends which are constructed according to the second invention, and effectively operable to coat a curved surface. Those rollers are attached to the tips of the arms of the coating robots 171 and 172. The output obstacles of CCVs (color change valves) 1 73 and 174, provided at the inlet of the coating booth, are connected to the pipes 1 75 and 176. The CCVs 173 and 1 74, different to the needle valve, allows and prohibits the supply of a type of coating material and selects one of the plural coating liquids by air change and unloads the selected one. . In this case, a coating material pipe 51 and a detergent pipe 153 are connected to the inlet of the CCV 173. The CCV 173 changes the pipe from one pipe to the other pipe by an air change each time it is applied. presents the need. Similarly, the coating material pipe 1 52 and the detergent pipe 1 53 are connected to the inlet of the CCV 1 74, and change the pipe from one pipe to the other pipe by an air change whenever the need arises . The CCVs 173 and 174 are provided at the inlet of the lining booth 170. If the CCVs are provided near the arms of the lining robots 171 and 172, the pressure fed liner rollers 171 a and 172a may be washed. on the same level with less consumption of the detergent. In Fig. 13, W indicates an object to be coated, such as an automobile, is transported to the coating booth 1 70 after it passed the inspection stage line and the masking step 3). The object is coated to have a protective film in the coating booth 1 70, and is subjected to the correction and finish coating step if necessary. P1 and P2 are workers who manually perform a pre-correction coating and a post-correction coating (finishing coating). The workers take the roller brushes R1 and R2 and the coating molds B1 and B2 in their hands, and manually coat the parts that could not be coated in the automatic coating process. The automobile W is finished coated if necessary, and transported from the coating coil 170 to the next coating stage 6). The components forming the automatic coating apparatus will be described in detail. Fig. 14 is a diagram for explaining a tank of liner material used in the second invention: and Fig. 14 (a) is a sectional view length inal showing the tank lining material; and Fig. 14 (b) is a cross sectional view showing the same. The coating material tank 1 1 5 is capable of storing a high quality coating material -68 which is free of the formation of a coating on the liquid coating surface, and can be reduced in size and simplified in construction . The coating material tank 1 1 5 includes a tank body 1 1 5 a which stores an aqueous coating material, a lid 1 1 5 b for hermetically sealing the tank body, a filling pipe 1 15 c for feeding a coating material water P to an aqueous coating material P stored in the tank body 15a, a supply pipe 15h, and a return pipe 1 55. The tank body 15a is a lower indium cylinder tank from which the tank is opened. upper side, it is coated with a material that has good water repellency, for example, Teflon. A sieve screen 1 1 5f is spread near the lower part 1 1 5e of the tank body 1 15a. The lid 1 1 5d is fixed towards the upper end of a single wall 1 15g of the tank body 1 1 5a and closes the tank body 1 15a. The filling pipe 1 15c and the return pipe 1 55 pass through the side wall 1 15g in different high positions at the measured height of the side wall 1 1 5g of the tank body 1 15a as shown in Fig. 14 (b). Accordingly, the aqueous coating material P flowing from the front ends of the filling pipe 1 1 5c and the return pipe 1 55 to the aqueous coating material, forms a turbulent to gentle agitation of the coating material aqueous P stored in the tank body 15a without rubbing air towards it. The discharge pipe 69 is connected to the lower part 1 15e of the tank body 1 15a. The coating material is supplied to the coating device in the coating booth 170 by the pump 1 16, and is applied to the coating film on the automobile by the robots and rollers of the second invention. The coating material left on the coating booth 1 70 is returned to the coating material tank 1 15 by means of the return pipe 1 55. When the coating material is consumed and a liquid level L of the aqueous coating material is used. P in the coating material tank 1 15 descends to a predetermined lower limit value, the pump 1 12 operates and the aqueous coating material P is supplied from the coating material mold 1 1 1 towards the tank of coating material 1 1 5 by means of the filling pipe 1 15c. When the liquid level L reaches a predetermined upper limit value, the supply of the coating material for the filling is stopped. The liquid level L of the aqueous coating material P in the coating material tank 1 15 originates to vary intermittently between the upper limit value and the lower limit value. The upper end of the tank body 15a is hermetically closed by the cover 1 15b. Therefore, it never happens that a space located above the aqueous coating material P inside the coating material tank 15 becomes excessively dry. The moisture in the space is placed in a wet condition at -70-where the humidity is 100% by the evaporation of water content from the aqueous coating material P. Accordingly, the coating material is prevented from drying out which is allowed to adhere to the inner surface of the side wall 115g, which is located above the liquid level L, and the coating material in the liquid level L. The aqueous coating material P on the inner surface of the lateral wall 115g and the liquid level L solidifies to measures, viz., the formation of the coating is avoided. During coating work, the aqueous coating material P in the coating material tank 115-is stirred slowly and gently by the coating material flowing therefrom from the front end of the return pipe 155. With stirring, it is prevented that the pigment contained in the coating material settles and coagulates, viz., a so-called cooking phenomenon arises. In addition, the front ends of the fill pipe 115c and the return pipe 155 project to the aqueous coating material P within the tank body 115a. With this feature, there is no opportunity to rub bubbles from the air into the coating material tank. Additionally, there is no need to use a separate agitation pump, and thereafter, the processing cost is low and there is no fear of rubbing bubbles from the air into the coating material tank. In this way, in the tank of material 71 formed in this manner, the upper part of the tank body 1 1 5 a which stores the aqueous coating material P is sealed with the lid 1 5 b. The space in the upper part within the body tank 15a is placed in a wet condition by evaporation of the water content in the aqueous coating material P. The aqueous coating material which flows from the filling pipe 1 15c and the return line 1 55 to the coating material tank 1 agitates the aqueous coating material P inside the coating material tank 1 to thereby prevent the presentation of the baking by the sedimentation of the pigment. According to the above, the coating material tank stores the coating material which is free of coating and cooking formation. In addition, there is no need to use the reflux bath and the agitation pump, and thereafter, the tank is simplified in construction and reduced in size. An example of the pump 1 12 used in the second invention will be provided. Fig. 1 5 is a longitudinal sectional view showing the pump 1 12 used in the second invention. In the Figure, the reference number 12 is designated to the pump. A non-curved part of the pump chamber 1 12B is not curved downwards from an upper collar 1 12H of the pump. A coupling bearing 1 12C is formed on the lower part of the non-curved part of the pump chamber 1 1 2B. A flow passage cavity 112E and a discharge passage cavity 112F are directed towards a lower collar 112D of the pump 112, while they are divided by a partition wall 112G. A suction valve seat 1122 is formed by varying from the flow passage cavity 112E to the latch bearing 112C. An upstream portion of the suction valve seat 1122 opens into the flow passage cavity 112E, and a downstream portion thereof opens toward the latch bearing 112C. The reference numeral 1123 is designated a valve seat body fixed on the latch bearing 112C. A suction side check valve receiving cavity 1125 and a discharge valve seat 1124, which face each other to the suction valve seat 1122, are divided by a partition wall 112W. An upstream part of the pump 112 opens to the non-curved part of the pump chamber 112B, and its downstream part opens to the support bearing 112C. A discharge side check valve 112U and a suction side check valve 112V are fixedly provided while being held firmly between the valve seat body 1123 and the catch bearing 112C of the pump 112. The check valve Suction side 112V is held firmly at the right end, and is facing the suction valve seat 1122. The discharge side check valve 112U is held firmly at the left end and faces the seat of discharge valve 1124. - 73 - A pump cover 1127 is located on the upper collar 112H of the pump 112, and a pump diaphragm 1128 is held firmly between the upper collar 112H and the pump cover 1 27. As described above, the lower surface of the pump diaphragm 1128 and the non-curved part of the pump chamber 112B define a pump chamber 112P. An upper surface of the pump diaphragm 1128 and a pump cover 1127 define a pulsation pressure chamber 112Q. A pulsation pressure guide passage 1129 opens into the pulsation pressure chamber 112Q. A pulsation tank cover 112M is located on a lower collar 112D of the pump 112. For the pulsation tank cover 112M, a first cavity 112J which faces the flow passage cavity 112E and a second cavity 112K that in front of the discharge passage cavity 112F are divided by a partition wall 112L. A pulsation diaphragm 112N is held firmly between the lower collar 112D and the pulsation tank cover 112M. A suction side pulsation diaphragm 112N1 is positioned between the flow passage cavity 112E and the first cavity 112J. A discharge side pulsation diaphragm 112N2 is positioned between the discharge passage cavity 112E and the second cavity 112K. With such a structure, the suction side pulsation diaphragm 112N1 and the first cavity 112J define a suction-side suction-74 tank, and the discharge side pulsation diaphragm 1 1 2N2 and the second cavity 1 12K define a discharge side pulsation tank. The suction side pulsation tank and the discharge side pulsation tank are divided by a partition wall 1 12L. The dividing wall 1 1 2L includes a communication passage 1 1 2R formed therein which communicatively interconnects the suction side pulsation tank 1 12J and the discharge side pulsation tank 1 12K. The discharge passage cavity 1 12F of the pump 1 12 is closed by the discharge side pulsation diaphragm 1 12N2 to form a discharge passage 1 12S. The flow passage cavity 1 12E is closed by the suction side pulsation diaphragm 1 12N 1 to form a suction passage 1 12T. The discharge passage 1 12S is connected to the coating material tank 1 15 (Fig. 1 3), and the suction passage 1 12T is connected to the coating material mold 1 1 1 (Fig. 13). The operations of pump 1 12 will be described. When a negative pressure is introduced into the pulsation pressure chamber 1 12Q by means of a pulse pressure guide passage 1 129 with the aid of the pump drive motor 1 12A (Fig. 13) or the like, the pump diaphragm 1 128 moves to a pulsation pressure chamber Q to increase a chamber volume of the pump chamber 1 12P and to reduce a pressure in the aqueous coating material P. Actually, the discharge side check valve 1 12U closes the valve seat of - 75 - discharge 1 1 24, while the suction side check valve 1 12V opens the suction valve seat 1 122. According to the above, the coating material in the mold of coating material 1 1 1 (Fig. 13) is sucked into the pump chamber 1 12P by means of the suction valve seat 1 122. A negative pressure is introduced into the pulsation pressure chamber 1 12Q by means of the passage pres guide pulsation ion 1 1 29. In turn, the pump diaphragm 1 128 moves to the pump chamber 1 12P, a volume of the pump chamber 1 12P is reduced, and a pressure inside the pump chamber 1 12P increases. As a result, the discharge side check valve 1 12U opens the discharge valve seat 1 124, and the suction side check valve 1 12V closes the suction valve seat 1 122. The coating material stored in the pump chamber 1 12P is discharged through the discharge valve seat 1 124 and the discharge passage 1 12S. When a pulsation pressure is continuously introduced from the pulse pressure guide passage 1 129 to the pulsation pressure chamber 1 12Q, the pump diaphragm 1 128 reciprocates in a continuous manner, and thereafter, a pressurized coating material is continually supplied. In a discharge stroke of the pump 1 1 2, the pressurized coating material is supplied from the chamber 76-pump 112P to the discharge passage 112S. In turn, the discharge side pulsation diaphragm 112N2 positioned opposite the discharge passage 112S is displaced towards the second cavity 112K upon receipt of the pressure, and a pressure in the second cavity 112K is increased. And, the increased pressure is introduced into the first cavity 112J by means of the communication passage 112R formed in the partition wall 112L to apply a pressing force to the suction side pulsation diaphragm 112N1, and to accumulate a pressure force towards the suction passage 112T in the suction side pulsation diagram 112N1. This is due to the fact of. that a compressive force is sealed in the pulsation tanks 112J and 112K. Thus, the pump enters in a suction stroke. The suction valve seat 1122 is opened by the suction side check valve 112V, and the coating material is sucked from the suction passage 112T and fed into the pump chamber 112P. At this time, the suction side pulsation diaphragm 112N1 in which a pressing force towards the suction passage 112T accumulates at the discharge stroke, travels to the suction passage 112T in a sudden attack, and the pressure is feed to the coating material from the suction passage 112T to the pump chamber 112P. As described above, in the pump 112 used in the second invention, the pump chamber 112P receives the coating material which is caused to flow by the base suction -77 - of negative pressure by the pump chamber 1 12P originated by the pump. displacement of the pump diaphragm 1 128, and additionally the coating material which is caused to flow by the pressure feeding action by the displacement of the suction side pulsation diaphragm 1 12N 1. Therefore, a large amount of coating material flows into the pump chamber 12P when compared to the conventional case. Then, the pump chamber 1 12P enters in a discharge stroke. In this stroke, the coating material stored in the pump chamber 1 12P is discharged to the discharge passage 1 12S through the discharge valve seat 1 124. Therefore, the amount of discharge coating material is increased mainly. While in the aforementioned case, the diaphragm pump capable of feeding a large amount of coating liquid is used, the pump is not limited to such a pump in the second invention, but any of the other types of pumps can be used. Examples of such are: a plenum pump in which the upper limit value of the coating liquid transport amount is greater to thereby allow a high speed coating (eg, JP-A-2001 -079812, JP -A-2001 -193592, JA-2001 -090676); a gear pump that has a characteristic of transporting exactly a fixed amount of coating material, and another characteristic that when a problem arises or maintenance is required, its replacement work is extremely simple and consumes a short time (JP -A-2002-005041, JP-A-1 1 -244767, and JP-A-1 1 -000589); a rotary pump characterized in that there is no loss of coating material, the service life is long, and the operability is good (JP-A-07-324684); and a Mono pump that imparts less limitation to project, and is capable of stably transporting a coating liquid through a long passage (JP-A-10-070972, JP-A-2002-273556, and JP-A- 2001-149838). A combination of the supply of coating material by the pump 1 16 in Fig. 13 and the proximity of the gun tip can be used. In this case, an exact additional amount is required. Those can be used in the types of pumps mentioned above. The description of the pump 1 12 provided for the mold of coating material 1 1 1 has been drawn up. The same pump can be used for the pump 1 16 for the coating material tank 1 1 5, and the pump 1 62 for the detergent cylinder 161. In this case, of those pumps, another pump can be used or those pumps by making better use of the characteristics of those pumps. A combination of those pumps can be used. In the aforementioned case, the pump is used to transport the lining material of the lining material tank 15 and the lining material liner 11. - 79 - For energy saving, it is useful to use. the own weight by gravity or a pressure when applying pressure to the upper side of the tank to transport the coating material. In addition, the pump 1 12 for the mold of coating material 1 1 1 can be omitted. In this case, a pump 16 for the coating material tank 1 15 is also used to transport the coating material from the coating material mold 1 1 1 to the coating material tank 1 15. FIG. 16 is a diagram showing an energy-saving coating material cycling system in which a pump is used to execute the functions of the two pumps. The cycling system of the energy saving coating material includes a coating material tank 1 1 5 'installed near the coating booth, a pump 1 1 6, a regulator 120, a solution filter 121 to filter the materials outsiders entering the lining material, a heat exchanger 1 30 to adjust the temperature of the lining material being transported, the pipes 1 51 and 1 52 which are connected to the lining devices in the lining booth 170, and a return pipe 155. The return pipe 1 55 branches to the pipes 155a and 155b in the position near the tank of coating material 1 15 ', and the pipe 155a is connected directly to the filling pipe 1 15c, and the pipe 1 1 5b is connected to the filling pipe 1 1 5c by means of an ejector pump 400. A change valve 470 is provided at the branch point of the pipes 80- 155a and 55b. The shift valve 470 includes a valve 471 and a support shaft 472. The valve 471 rotates the line 155a or 1 55b around the support shaft 472. When the valve 471 is turned towards the line 155a, the line 1 55b is opens. When this is turned into the pipe 155b, the pipe 155a opens. The front end of the filler pipe 1 1 5c projects towards the aqueous coating material P in the coating material tank 1 15 '. As shown in Fig. 14 (b), the filler pipe 1 1 5c is curved along the sidewall in the circumferential direction within the material tank of. coating 1 15 '. Accordingly, the aqueous coating material P flowing to the aqueous coating material from the front end of the return pipe 155, forms a gentle turbulent agitation of the aqueous coating material P stored in the tank body without rubbing. air towards it. According to the above, the agitation of the coating material depends only on the kinetic energy of the coating material transported from the filling pipe 1 15c. The supply pipe 1 15h extending from the bottom of the coating material tank 1 1 5 'enters the coating booth 170 through the pump 1 16 and the similar branches to the pipes 151 and 152 connecting to the coating rollers fed to pressure 171 a and 172a in the coating booth. The return pipe 155 for the remaining coating material branches to the pipes 1 55a and 1 55b. The piping 155b extends through the ejector pump 400 and returns to the coating material tank 115 '. The ejector pump 400 is incorporated into the pipe 155b as one of the pipes of the return pipe 155, and its suction port 410 is connected to the coating material mold 111. The ejector pump includes an inlet 420 for receiving the material coating from the pipe 155b, and an outlet 440 from which the coating material flows. From the suction port 410, the suction port 410 and the outlet 440 communicate with the pump chamber 450. The front end of the flow line 430 extending from the inlet 420 is facing an internal funnel surface 460 formed on the wall of the pump chamber 450. According to the above, when the coating material flows from the pipe 155b to the inlet 420, flows through the flow pipe 430 and flows out of the outlet 440, a negative pressure originates in the vicinity of the inner funnel surface 460. The Coating material in a connecting pipe 111a, viz., the coating material in the solid cylindrical body 11, is sucked into the pump chamber 450 through the suction port 410. Both coating materials flow out of the outlet 440 to the fill pipe 115c, while mixing, and finally fed into the coating material tank 115 '. In a normal operation, the valve 471 of the shift valve 470 is rotated from the tube 155a to the pipe 155b around the support shaft 472. Accordingly, in this case, the pump 16 operates for feeding the coating material to the coating booth 170 where the coating material is consumed. The remaining coating material flows from the return line 1 55 and flows through the pipe 1 55a and the filling pipe 1 1 5c, and finally is collected to the coating material tank 1 15 '. With progress of the operation, the amount of the coating material in the coating material tank 1 15 'is reduced, and when an liquid level sensor (not shown) detects that the liquid level drops below a liquid level. By default, valve 471 of shift valve 470 is rotated from line 155b to line 1 55a around support shaft 472. As a result, line 1 55a closes, and line 155b opens, so that the coating material flows from the return pipe 155 to the ejector pump 400. In the ejector pump 400, the coating material in the coating material mold 11 11 is sucked into the ejector pump 400 by means of the discharge pipe 400. connection tube 1 1 1 a by the action of the ejector pump 400. Subsequently, both coating materials are mixed and introduced into the coating material tank Í15 '. In this way, the coating material can be easily transported from the mold of coating material 11 to the tank of material 1-5 'without using another pump. In addition, the use of the ejector pump 400 considerably reduces a space required for the transportation of the coating material. A further advantage is that little electric power is required for the operation of the ejector pump 400, and this fact contributes to the saving of energy, and the operating cost is remarkably reduced. An example of the filter used here will be described. Fig. 17 shows a filter of coating material that makes it hard for a sedimentary material in the coating material to precipitate on the bottom thereof. As shown in Fig. 17, in a lining material filter 500, a head 51 1 is provided with joints 501 and 502 on both sides thereof. Those joints are connected to a feeding step of coating material. A bark 513 includes a lower plate cover 512 under the head 51 1. The bark 513 is fixed to a filter housing 51 5 with the aid of a roller 514. An empty filter cartridge 503 is placed inside the filter housing 515. The coating material enters the filter of coating material through a filter. inlet nozzle 51 1 a of head 51 1, which communicates with joint 501 at the inlet. Then, the coating material enters a filter cartridge 503 from its outer periphery, moves towards the center of the filter cartridge, and exits therefrom. At this time, the filter cartridge - 84 - filters the foreign material from the coating material. Thereafter, the coating material moves upwards in the empty space of the filter cartridge 503, and pressurized from the joint 502 near the outlet to the coating material supply passage. The reference number 504 is a guide spring for attaching the filter cartridge 503 at a predetermined position within the shell 513. Reference number 505 is designated to the connection parts for connection to various types of measurement verifiers. In the liner material filter 500 thus constructed, when the filter cartridge 503 is replaced with another cartridge, a notch 516 provided in the tip of the roller 514 is released, the rind 513 is removed from the head 51 1, and the 503 filter cartridge is replaced with another cartridge. In this way, when the solution is supplied, the filter body is placed at the top on the solution supply side. Therefore, there is no opportunity for the sedimentary material of high gravity within the coating material passing through the filter body to precipitate and accumulate in the filter body. The heat exchanger 1 30 for controlling the temperature of the coating material will be described. A requirement of the coating material preparation chamber 1 00 towards the coating booth 170 is relatively long. In a winter season, the pipe is cold, so that when the coating material reaches the coating coil 170, the temperature of the coating material is also low. In this state, the viscosity of the coating material becomes high. When under the bright summer sun, the temperature of the coating material is excessively high, a drying rate of the coating material is excessively high. This is also undesirable. In order to maintain the liquid temperature of the coating material at a suitable temperature, the heat exchanger 130 can be provided in the middle part of the transport path of the coating material. With the provision of the heat exchanger, the coating work can be performed stably through all seasons. A heat exchanger described in Japanese Patent No. 31 20995 can be incorporated, like heat exchanger 130, into the roller coating device. Fig. 18 is a diagram showing a heat exchanger used in the second invention. In Fig. 1 8, the outlet of the coating material of the solution filter 1 21 (Fig. 13) passes through a primary coil 1 36a of the heat exchanger 1 36 and flows to a liquid quantity stabilizer 140. The warm water and water The cold water is mixed and fed to a secondary coil 136b of the heat exchanger 136. A cold water supply means is formed in which the cold water is sucked through a cold water tank 1 31 a and a water tank. cold 132a, and passes through pipes 133a, 133c and 133e, and returns to the original place. A lukewarm water supply means is formed in which warm water is sucked through a tank of warm water 1 31 b and a tank of warm water 132b, and passes through pipes 1 33b, 133d and 133f. The secondary coil inlet 136b of the heat exchanger part 1 36 is connected to a three way valve 134a by means of a feed tube 1 36c. A discharge side of the secondary coil 1 36b is connected to a three-way valve 1 34a through a discharge pipe 1 36d. An instrument (not shown) for measuring the temperature of a fluid in the tube and a temperature adjuster are coupled to a pipe 151 (Fig. 13) varying between the heat exchanger part 136 and the coating booth 170 (Fig. 13). An opening of the three-way valve 134a is controlled by an output of the temperature adjuster. A measuring instrument (not shown) for measuring the temperature of a fluid in the discharge tube 136d near the three way valve 134a and a temperature adjuster, are provided. An opening of the three-way valve 134a is controlled by an output of the temperature adjuster. The operation of the heat exchanger constructed in this way will be described. When the coating material passes through the pipe 51, the measuring instrument detects the temperature of the coating material. When the measurement result shows that the liquid temperature is low, the opening of the three-way valve 134a is controlled according to the measured temperature to increase the amount of warm water fed to the heat exchange part 136 and to reduce the amount of cold water fed. When the measuring result of the measuring instrument shows that the temperature of the coating material is excessively high, the three-way valve 134a is controlled to increase the amount of cold water fed to the heat exchanger part 136, and to reduce the amount of warm water fed. In this aspect, the temperature of the coating material is controlled by adjusting the three-way valve 134a and thereby adjusting the amounts of a cooling medium and a heating medium to be fed to the heat exchange part 136. There is a where the temperature of the coating material has been adjusted, but the temperature of the coating material is abruptly reduced for a certain cause. In such a case, the opening of the three-way valve 134a is controlled in order not to feed a refrigerant to the heat exchange part 1 36. And, the opening of the three-way valve 134a is controlled in order to feed continuously a maximum amount of heating medium to the heat exchange part 136. In this aspect, the temperature of the coating material can be adjusted by adjusting the medium amounts of -88-heating and cooling. In the heat exchanger 1 30, it is required to adjust the temperature of only the minimum amount of coating material. In this regard, the heat exchanger is of an energy-saving type. In the event that the coating material does not require a full-scale heat exchanger as shown in Fig. 18, an air conditioner for temperature control of the coating material preparation chamber 100 can be used. an alternative, the tank body 1 1 5a is designed to have a double structure. The coating material is processed to pass through the interior of the tank body. The side of the double structure is heated and controlled by steam or warm water. If a coating liquid is made of a material whose viscosity is insensitive to the liquid temperature, you do not need to use the heat exchanger or the like as a matter of course. In the aforementioned case, the coating material left after it is fed to the two automatic coating apparatuses is returned to the coating material tank 1 1 5 by means of the return pipe 155 (circulation method). However, it is preferable to employ a terminal method in which only the amount of coating material to be used is fed to the two automatic coating devices 89, and the coating material as it is fed is used up to the second apparatus. automatic coating By doing so, there is no fear of bubbles being rubbed during the course of the circulation of coating material. As for the material of pipes 1 51 and 1 52, the return pipe 155, the detergent pipes 1 53 and 154, the pipes 1 75 and 1 76 for the coating rollers fed at pressure from both ends, since the portions that are contacted with the coating material, such as pumps, regulated, CCVs and horses, are placed under pressure, those portions are preferably made of stainless (SUS), and Teflon or nylon pipes can be used for portions that are not placed under high pressure. In this automatic coating apparatus, as in other coating apparatus, a flow rate of the coating material sometimes vs by viscosity vtion of the coating material, the adhesion of the coating material to the steps, and the like. For this type of flow rate stabilizer control of the coating material, a feedback control is generally employed, which minimizes an error, or a difference between a target value of flow velocity determined by the characteristic aqueous coating material, the amount of coating material discharge and the like and a current flow velocity value measured by a flow meter. A - 90 - PI D adjuster or a microcomputer as described in JP-A-63-54969 may be used for the control unit. In the stabilizer of the conventional flow velocity, a response of the flow meter is not satisfactory or the liquid flow is not stable, from now on, it is difficult to ensure high speed and stable control when the flow rate of the coating material vs, or when the liquid flow is interrupted especially when the operation of the liquid discharge means, such as the coating rod, is turned on and off. To compete with this, a high response non-contact type flow meter can be used. However, such a flow meter is generally expensive and large in size and weight, and easy to operate erroneously when subjected to vibrations or the like. Therefore, when the flow meter is applied to the automatic coating apparatus, problems will e. For this reason, the control method in use for the rolling gun, described in JP-A-7-2321 1 2, was modified for the coating roller and used for flow rate control. The result was that the stabilization of the flow velocity was ensured, which is able to perform a stable flow rate control irrespective of the response performance of the flow velocity. This method of controlling the stable flow velocity will be described with reference to the related drawings. Fig. 1 9 is a block diagram showing a liquid quantity stabilizer used in the second invention. In the figure, the reference number 140 is a liquid quantity stabilizer; 141 is a control valve type operation by air; 142 is a flow meter; 143 is a counter; 144 is a barrier amplifier; 145 is a similar memory unit; 146 is an adjuster; and 147 is a converter. A coating material flowing out of the coating material tank 115 (Fig. 13) reaches the liquid quantity stabilizer 140 by means of the heat exchanger 130 (Fig. 13). In this case, the coating material flows through the air operation type control valve 141 and the flow meter 142, and the CCV 140 in FIG. 13, and finally is discharged to an object to be coated, from the coating rollers fed by pressure. automatic 171a and 172a. The automatic pressurized cladding rollers 171a and 172a are moved back and forth in liaison with the motor conduit, the electromagnetic valve, and the like, in response to the control signals of the coating robots 171 and 172. roller discharge air for the automatic pressurized coating rollers 171a and 172a are switched on and off in their supply in connection with the electromagnetic valve line. The driving control signals (on / off signals) for the electromagnetic valve, which flow out of the coating robots 1 71 and 1 72, are sent to a counter 143. The flow meter 142 generates a pulse signal having a frequency based on a coating material flow rate l, and the pulse signal is supplied through the counter 143 and the barrier amplifier 144 to an analog memory unit 145 having conversion media D / A and storage media. The counter 143 receives a pulse signal from the roller 1 2 and the on / off signals from the coating robots 171 and 1 72, and generates a control signal for the analog memory unit 145. The counter 1 43 responds to a conduction edge (transient from an off state to an on state of a signal) or to a signal from each of the coating robots 171 and 172, and begins a counting operation of a . pulse signal derived from the flow meter 142. When a number of pulses reaches a predetermined value, the counted one places a control signal in an on state, the signal on the way to the analog memory unit 143 placed in the trajectory of feedback and mentation. A count value of the counter 143 is reset to zero in response to a traversing edge (transient from the on state to the off state) of a signal from each of the coating robots 1 71 and 172, and the counting operation in response to the driving edge (transient from the off state to the on state). The counter which is reset in its contents and re-initiates the counting operation in response to the leading edge of the signal from each of the coating robots 171 and 172, can be used for the counter under discussion. The analog memory unit 145 outputs a current having a value corresponding to the signal as an input when the control signal of the counter 143 is placed in an on state. When the control signal is placed in an off state, the analog memory unit maintains a current value corresponding to the input signal received at that moment and outputs a current signal having that value. An output signal from the analog memory unit 145 is applied as a value of a measured flow velocity of the liquid to an adjustment meter 146. The adjustment meter 146 is in the form of a PID adjustment meter for controlling an aperture of the air operation type control valve 141, viz., to control PID a liquid flow velocity. The adjustment meter 146 includes a display device for representing a predetermined value of flow rate (target value) and an input valve (feedback value) derived from the analog memory unit 145. The adjustment meter 146 compares the value Default with the inlet valve, and outputs a control signal corresponding to an error, and its output signal is supplied to the converter 147. The converter 147 adjusts the compressed air pressure supplied to the same through a reduction valve in accordance with a output signal level of the adjustment meter 146, and supplies it as a control air for the air operation type control valve 141. The air operation type control valve 141 adjusts a valve opening according to a pressure of compressed air supplied, such that a flow rate of coating material is controlled in order to minimize a difference of the inlet valve from the predetermined value independently of environmental factors, such as adhesion of coating material to the passage of material from coating. The operation of the liquid quantity stabilizer constructed in this way will be described. Fig. 20 is a timing diagram showing a variation of a flow velocity of an aqueous coating material with respect to time in the liquid quantity stabilizer of Fig. 19, and the operations of the respective portions in the device . The coating rollers 171a and 172a (Fig. 13) are ignited for a period of time t3 and turned off for a period of time 114 according to the control signals of the coating robots 171 and 172 (Fig. 13). The analog memory unit 145 is a clamped state in which a measured value stored in the present is let out for a period of time that the coating rollers 171a and 172a are in an off state. At a time point tA, the coating rollers 171a and 172a-95 are in an on state. At a time point tB after a period of time t1 that the counter 143 counts a predetermined number of pulse periods, the analog memory unit is placed in a state through which a current value corresponding to a valve is allowed to exit. of input measurement. In the case where the coating rollers 171a and 172b are placed in an off state at the time point etc., the analog memory unit 145 is placed in a holding state and maintains a preceding feedback amount. During a period t2 from a time point tB to a time point tC, a feedback control through the adjustment meter 146 is performed. During periods other than period t2, an open cycle control is performed based on a holding value of the analog memory unit 145. For example, two different values (determined by the proportional sensitivity P, an integration time I and a Differentiation time D) are set in the adjustment meter 146 in order to define its operation. When the coating rollers 171a and 172a are in an off state, a first predetermined value is selected, and when those rollers are in an off state, a second predetermined value is selected. There is a case in which a target flow rate value is somewhat different from a flow rate value stored in the analog memory unit 145. In such a case, if the -96-second default value remains unchanged, the adjustment meter 146 will correct the difference and change a control air pressure. At this time, a value input for the adjustment meter 146 is a fixed value stored in the analog memory unit 145. Therefore, the difference is not corrected, and the control air pressure continuously changes. To avoid this and stabilize the control system, the first predetermined value is set to a suitable low response value. The second predetermined value is a predetermined value for uniformly correcting the difference in the measured flow velocity of the target flow velocity. If the answer is too high, the stability of the control system is lost and vibration occurs. Conversely, if the response is low, the correction operation is slow. To avoid this, a value. suitable is selected according to a control characteristic required for the system. The operation of the liquid quantity stabilizer when discharging flow rates of the coating rollers 171a and 172a, a small change will be described. It is assumed that under conditions that the coating rollers 171a and 172a are in an ignition state (operation), and the discharge flow rate is maintained at 200 cc / min. by the feedback control, a number of pulses coming out of the flow meter 142 is 222 pulses / min., an output level of the analog memory unit 145 when it is in a - 97 - complete state, is 7.2 mA, an output level of the adjustment meter 146 is 112 mA, and the control air pressure derived from the converter 147 is 0.45 kgf / cm2 (tester pressure: the same will apply hereinafter). In this confirmation, even if the coating rollers 171a and 172a are placed in an off state, the current of 7.2mA is maintained in the analog memory unit 145, and this current is let out. According to the above, the control air pressure to the control valve 141 is maintained at 0.45k g f / cm2. As shown in Fig. 20, when the coating rollers 171a and 172a are placed in an on state at a time point tA, since the flow meter 142 has a response delay, an output signal from the unit Analog memory 145 should rise after a time t ', as indicated by a »chain line of a point in the figure. The analog memory unit 145 maintains a measured valve (7.2 mA) at a time point where the coating rollers 171a and 172a are placed in an off state while the control signal of the counter 143 is in a state of off. And it lets out the measured value to the adjustment meter 146. The control air pressure is maintained at 0.45k g f / cm2. According to the above, the discharge flow rate of each of the robots 171 and 172 is rapidly raised to 200 cc / min. At this time, the PID value of the adjustment meter 146 changes its value to the second predetermined value (No. 2 in the figure) is effective for - 98 - improving the response operation. Presently that period of time that the output signal of the flow meter 142 establishes down and becomes sufficiently stable, viz., The period of time t1 (>.; t ') defined by the counting value of the counter 143, elapses, and the operation of the flow meter 142 is stabilized, a closed cycle control is performed by using its output signal as a feedback quantity. When the coating rollers 171a and 172a are placed in an ignition state at a time point te, the output signal of the flow meter 142 drops. Also in this case, a "level of an input signal to the analog memory unit 145 does not fall quickly since a response delay t" is presented. To compete with this, immediately after the coating rollers 171a and 172a are placed in an off state, the. Analog memory unit 145 is placed in a clamped state to maintain the 7.2 mA output. The output clamp synchronization can be set at a point of time preceding the dropping synchronizations of the coating rollers 171a and 172a within a range where no disadvantage occurs. During the shutdown period of the coating rollers 171a and 172a, the PID value of the meter is adjusted 146 to the first predetermined value (No, 1 in the figure). Therefore, a fixed control air pressure is stably applied to the air operation type control valve 141 while it is free of alteration. And a transient operation stabilizes at the next point a-99-time. As a result, a similar operation is repeated. The description about the operation of the liquid quantity stabilizer is given below when the discharge flow velocities of the coating rollers 171 a and 172a vary for a reason that, for example, the coating material adheres to the material flow path. aqueous coating. The description will be given with reference to Fig. 21. It is assumed that as shown in Fig. 21, the flow rate of coating material required still the coating rollers 171 a and 1 72a become dropped from 200 cc / min, which is originally required, to 1 80 cc / min. A period t1 '(> t') is performed which varies from a moment that the coating rollers 171a and 172a are placed in an on state, defined by a count value of the counter 143, a cycle control; The flow rate of the coating material is 180 cc / min. After the period elapses, the analog memory unit 145 applies an output signal (e.g., 7.2 mA) corresponding to a measured value of the flow meter 142 (200 pulses / 5 min., Corresponding to 180 cc / min. of the flow rate) for the adjustment meter 146. As a result, an output value of the adjustment meter 146 increases from 1 1 .2 mA to 12 mA, the control air pressure of the converter 147 is increased by 0.45 kgf / cm2 to 5.05 kgf / cm2, through - 100 - which a desired flow rate of 200 cc / min, is obtained by adjusting the opening of the control valve. And, when the discharge amount or flow rate of each of the coating rollers 171 a and 1 72 a is equal to a predetermined value, the flow meter generates a number of pulses corresponding to its value. According to the above, the analog memory unit 145 outputs a corresponding value (7.2 mA). In this state, a difference of the measured value from the target value does not occur. According to the foregoing, the adjustment meter 146 maintains an output value (12 mA) at that time. The analog memory unit 145 maintains its value even when the coating rollers 171 a and 1 72 a are placed in an on state. Then, by consequence, the control is performed in such a way that a desired current is produced at the beginning of the ignition state of the rollers. As described above, in the liquid quantity stabilizer, even if the flow of the coating material is interrupted by the on / off of the coating rollers 171 a and 172 a, the coating material is uniformly discharged when the ignited state is raised, and a stable control is ensured. A number of pulses that the flow meter generates according to a flow rate is counted, and the feedback control is executed based on the count value. If a count value by counting the number of pulses defined by the type of flow meter is established as an initial value in the electronic counter, there is no need to change a predetermined time - 1 01 - of the synchronizer according to a change of the amount of discharge. The number of items to be set for the system by the operator is reduced, and complicated operations are avoided. In some coating conditions, it is required to frequently repeat the on / off of the coating discharge for the coating roller. In such a case, a current measured value of the discharge quantity measured by the flow meter inserted in the coating step is fed back to the control device as described in JP-A-5-50013. The control device is compared to the measured value with a predetermined amount of discharge amount, which is determined in advance to the base of various coating conditions, such as types of coating material and an object to be coated. A regulator of coating material inserted in the step of. Coating material is adjusted based on the comparison result to thereby control the amount of discharge to a predetermined value. This control process is carried out for a first fixed period when the coating conditions change and the coating material begins to feed. Accordingly, during the coating operation under the same coating conditions, it is preferred to keep the coating material regulator in a state of the end of the control time. In this aspect, the coating operation under the new coating conditions are prepared. Then, the control device is operated for a fixed period of time to cause the spray gun to continuously spray the coating material. During this period, the discharge quantity is measured by the flow meter, and a measured value is fed back to the control device. The control device compares the measured value with a predetermined value corresponding to the coating conditions. The coating material regulator is adjusted according to the comparison result to control the discharge amount to the predetermined value. When a fixed period of time elapses, the function to adjust the?; regulator of coating material of the control device as the need stops, and at the same time, the regulator of coating material remains in a state of. final adjustment of the control time. Consequently, the operation of, -. Coating is done under the same conditions. During this operation, the finally controlled discharge quantity is maintained. Even when the ignition / shutdown of the roller coating discharge is repeated frequently, the coating operation is performed in a fixed discharge amount at all times. For the coating conditions, the same thing is also true for the case of the change between the coating material and the detergent by the CCV, which is used in the second invention. An operation control of the coating roller will - 103 - describe. For cladding of the press-loaded roller clamping device of both ends / press-fed from one end according to the second invention to a driving device, the cladding roller cladding device is pressurized at both ends / fed at the pressure of one end by itself is as follows to a curved surface in motion, as will be described later. Therefore, there is no need to use the high precision and charge driving device, and a general purpose robot apparatus can be used for the driving device It is satisfactory to use such operation control as being able to control the object Coated and the pressure force of the roller A suitable robot can be suitably selected from among the robots: multi-articulated, such as the axis 6 robot, and the single axis robot according to the use. Reciprocating coating using the pressure fed roller coating device at both ends / fed at one end pressure, the invention described in Japanese Patent No. 2514856, can be used As described above, the coating process using the Coating rolls can be automated by using the coating booth 1 70 according to the second invention. to the third - 104 -invention will be described. As described above, when a rectangular area is coated, a coating film on the peripheral edge of the rectangular area is thicker than the remaining part. The cause of such was investigated. The investigation clarified the cause. Fig. 22 is a diagram for explaining a coating operation performed by the coating roller fed under pressure according to the first invention. Fig. 22 (a) shows a right directional coating process, which is carried out by the pressure fed coating roller attached to a robot arm; and Fig. 22 (b) shows a process of left directional coating carried out by the same. In the figure, 221 is a coating robot arm; 222 is a pressure-facing clamping roller operable by curved surface attached to the tip of each arm of the coating robot arm 221; 223 is a roller coating brush fed by pressure; and 224 is a coated surface; and P is coated coating material. In the same coating direction, when a stump of the coating robot is rotated 180 ° of a state (a), the feed roller is directed as in a state (b). When the feed roller moves back from the state (b), an effective coating target is obtained, and the coating time is reduced. The feed roller can move backwards - 105 - while it is in the state (a), v / 'z. , and it moves reciprocally. A double coating roll which is a combination of the coating roller supplied under pressure in the state (a) and the coating roller fed under pressure in the state (b) can be used. Fig. 23 is a diagram for explaining an automotive tire covering by a conventional coating method: Fig. 23 (a) is a plan view for explaining an order of coating operations; and Fig. 23 (b) is a cross-sectional view showing the result of the coating operation. In Fig. 23, for coating a car cover in a wide rectangular area, the pressure coated roller brush 10 is placed at the left end of a first long area indicated by (1) with the robot. coating 171. The roller brush of the pressure fed roller, which is in the state (a) of Fig. 22, moves from left to right, while the area is coated (ON), and stops at the right end. Then, the pressurized roller coating brush 10 is raised and rotated with the coating robot 171; the fed roller brush is placed at the right end of a long area (2); the roller brush fed, which is in the state (b) of Fig. 22, moves from right to left, while the area is coated (ON), and stops at the - 106 -extreme left. As a result, the roller coating brush 10.0 is raised, and is placed on the left end of a long area indicated by (3) with the coating robot 171; the roller brush fed, which is in the state (a) of Fig. 22, moves from left to right, while the area is coated (ON), and stops at the far right. Next, the pressurized roller coating brush 10 is raised and changed with the coating robot 1 71, and is placed on the left end of a long area (4) with the coating robot; the roller brush fed, which is in the state (b) of Fig. 22, moves from right to left, while the area is coated (ON), and stops at the far left. As seen from Fig. 23 (b) showing a thickness distribution of a coating film P 1 thus coated in a longitudinal section, a thickness P 12 of the coating film is thin in a central portion of the film. rectangular area since the roller coating brush fed at pressure 10 moves on and along the central portion. At the ends of the rectangular area, the roller coating brush supplied with pressure 1 0 temporarily stops. Accordingly, a paralyzed coating material is formed therein, and a thickness P1 1 of the coating material is relatively large. Sometimes, this causes buckling of the lining material under the influence of configuration and slope. A coating method that is capable of normally coating an object to be coated without the formation of uncoated portions or excessively coated parts on the object surface, and when using the coating material efficiently and economically, is described in the document. Patent 2. In this technique, a spray gun of coating material, which is confronted with a part of the brush of a coating brush for rollers having a core part and a brush part, sprays the coating material to an external surface of the brush part to thereby feed the coating material. In addition, complicated work to locate a coated object: model, is required. In this aspect, the technique described is not suitable for the automation of the coating work. (1) Consecutive steps of the automatic coating apparatus The pre-stages of forming a protective film to protect a coating film of a motor vehicle are as follows: 1) Cleaning a car by washing water; 2) drain the washing water; 3) masking the carriage body except a part thereof on which a protective film will be formed; 4) coating a protective film; 5) perform a correction and finishing coating if necessary; and 6) drying the coated carriage. If a - 108 - car surface does not stain, steps 1) to 3) can be omitted. (1) A car W on which a protective film is formed is subjected to a washing step. In the stage, the carriage body is completely washed by a tub washing machine of the tub type using a rotating brush, in order to remove the rainwater, the dust and the adhesion similar to the surface of the film. coating. In the cold season, water droplets attached to the coating film surface freeze to possibly damage the coating film surface. To avoid this, lukewarm water of 30 to 50 ° C is used for washing. (2) In the step of draining washing water following the washing step, the washing water left on the surface of the car coating film W, which is washed in the washing step, is removed from the washing stage. blow the hot air of approximately 30 to 70 ° C on the coating film surface. The warm water used in the washing step and the hot air used in the washing water drain stage make good the coating of an aqueous coating material, which is carried out in a coating stage as a post stage. . Therefore, a surface temperature of the automobile is suitably maintained. The surface temperature of the automobile is 1 5 ° C or more, preferably 20 to 30 ° C in consideration of the formability of the film of the coating material. (3) In the next masking step, to mark -11- the limit between a coating area to be coated with an aqueous coating material and a non-coating area, a tape is applied to the surface of the automobile W having the wash water drained and dried in the washing water drain stage. The open intake duct in the engine cover, and non-lining parts, e.g., resin parts, located within the lining area, are covered with a cover or the like. (4) In the coating step, the coating area defined by the tape in the masking step is coated with an aqueous coating material mainly, containing acrylate emulsion (eg, "Wrap Guard L", made by Kansai Paint Corporation) when using the roller brush coating device according to the second invention. (5) In the next step of finishing coating, which can be carried out if necessary, the tape applied in the masking step is peeled, and the cover is removed. In a finishing coating, the small uncoated portions in the coating area are manually coated with an aqueous coating material by using a brush or small roller brush. The masking step, the coating step, and the finishing coating step are carried out inside the coating booth. (6) In the subsequent drying step, the coated carriage is placed in an IR drying oven, and irradiated with -10-infrared rays for approximately 30 to 90 seconds, thereby improving the drying of the aqueous coating material. coated including the inside of it. Accordingly, the aqueous coating material is dried by uniformly heating the entire coated carriage body when using a hot air drying oven or by using only the hot air drying oven, thereby forming a protective film. Where the hot air drying oven is used, it is preferred to dry the coating material for approximately 210 minutes under conditions that a drying temperature is 50 to 1000 ° C and a hot air speed is 0.5 to 8 m. / sec , to ensure a satisfactory film formability of the aqueous coating material and to protect the bonded components such as various types of electrical components. The aforementioned steps can be replaced by online stages. In this case, after the coating stage (intermediate coating and finishing) of the car ends and an inspection stage ends, the car body is coated with the protective coating material, and dried, and from there the components such as the meters they join the car, through which a finished car is presented. The "coating material" used herein is a coating material for forming a coating film to protect the coating of the carriage body. A viscosity of the coating material is higher than that of the material of normal color. Accordingly, it is difficult to make such a coating for the formation of the protective film by using a conventional spray-type automatic coating apparatus. For this reason, the manual work that uses the coating roller is used for the coating. The automatic coating roll according to the first invention presented by the Applicant of the present present Application allows the steps of forming a high viscosity protective film to be automated. The automatic coating apparatus is used to automate the coating step 4) of those steps 1) to 6). The flattening of the roller is carried out before the coating method according to the third invention; 2) Roller Flattening: Fig. 24 shows an example of a roller flattening device: Fig. 24 (a) is a perspective view showing the roller flattening device as viewed diagonally upward from the front; Fig. 24 (b) is a side view of the roller flattening device as seen from the right side in Fig. 24 (a); and Fig. 24 (c) is a perspective view of the roller flattening device as viewed diagonally upwards in Fig. 24 (b). In the figure, the reference number 90 is a roller flattening device, and 91 is a coating roller fed under pressure. 92a and 92b are contact rollers; 93a and 93b-1 1 2 - are rotary axes of the contact rollers 92a and 92b; 94a and 94b are gears; 93 is a driving gear for driving the gears 94a and 94b; 96 is a motor for rotating the drive gear 95; and 97 is a mounting plate for mounting the gears 94a and 94b and the motor 46. When the motor 96 is driven to rotate, the driving gear 95 rotates and then the following gears 94a and 94b rotate in the same direction and at equal speeds. . According to the above, the pressure-fed coating roller 91 placed on the previous limit the follower gears 94a and 94b by gravity, also rotates. When the pressurized coating roll 91 in which a coating material which has accumulated in a lower part of the brush by gravity is rotated several times, the material. of coating is evenly distributed over the entire surface of the roller. Thereafter, the coating material is applied to the coated object by the pressurized coating roll 91 to thereby form a uniform coating film in thickness. Fig. 25 is a conceptual diagram that typically shows how a roller flattening device in Fig. 24 is used by the coating robot inside a coating booth. In the figure, the reference number 90 is a roller flattening device according to a first embodiment; 171 and - 113 - 172 are coating robots; 171a and 172a are pressure-fed facing rollers at either end or one end attached to the tips of the arms of the coating robots 171 and 172; 173 and 174 are CCVs attached to parts near the tips of the arms of the coating robots 171 and 172; K is coating material recovery bath; and W is a car as an object to be coated. Prior to the coating operation, the pressure-fed coating rollers 171a and 172a receive the coating material of the solid cylindrical body 11 (Figs 13 and 14). In this; At this time, the coating material on the pressure-fed coating rollers 171a and 172a has been diverted to a lower part by gravity. The pressure-fed coating rollers 171a and 172a are transported upwards from? roller flattening device 20 by coating robots 171 and 172, and placed on the contact rollers. Thereafter, the contact rollers are rotated to evenly distribute the coating material over the pressure fed coating rollers 171a and 172a. Thereafter, the coating method according to the third invention is executed. The coated object can be washed on the roller flattening device, and was made to wait. At rest, the median cavity, and the operating end of the automobile line, the coated object is preferably washed on the roller device. After washing, you can wait. Coating method of the third invention: Fig. 26 is a diagram for explaining a coating method of the third invention when using the covering of a car cover: Fig. 26 (a) is a plan view to explain an order of coating operations; and Fig. 26 (b) is a cross-sectional view to explain the result of the coating. In Fig. 26, for coating a large rectangular area A1 of a car cover 1 1, the pressurized liner roller brush 10 is placed at the left end of a first long area indicated by (1) with the coating robot 1 71 (Fig. 1 1). A difference between the long area (1) in 'Fig. 26 and the long area (1) in Fig. 3 in the conventional coating method is as follows: In the conventional coating method, the left end of the long area (1) is the left end of the broad area A1. In the coating method of the third invention, the coating operation starts at a point located within the left end of the wide area A1 by a maximum distance corresponding to the width of the coating roller fed under pressure (This point will be referred to as a "dot left inside "). In other words, the coating operation starts from a point located internally by a distance corresponding to an area larger than half the area corresponding to the long area (8) in the figure. - 1 15 - The same is true for a point where the lining of the long area (1) ends. In the conventional coating method, the end point of coating of the long area (1) is the right end of the wide area A1. In the third invention, the coating ends at a point located internally by a maximum distance corresponding to the width of the coating roller supplied under pressure from the right end of the wide area A1 (this point will be referred to as "right inner point"). In other words, the cladding advances to a point located internally by a distance corresponding to a larger area, than half the area corresponding to the long area (7) in the figure. Then, the coating robot 1 71 lifts the pressure-fed coating brush 10 and is rotated, and pushed on the right inner point of the long area (2). The brush for coating rollers fed by pressure in a state of FIG. 22 (b) is coated (ON) from the right to the left while the coating material is discharged, and is stopped in the left inner point. Consequently, the sequence of coating operations is repeated. In the long area (6) of the final line, the coating robot 171 lifts the roller brush for pressurized coating 10 at the inner right point of the long area (7), and rotates it, and pushes on the inner point right of the long area (6), and the coating roller pressurized in the state of Fig. 22 (b) is rolled from the right to the left. - 1 16 - In the right inner point of the long area (7), the coating robot 171 lifts the roller brush for pressurized casing 10 and rotates it, and pushes it in the right inner point of the long area (6) , and the coating roller pressurized in the state of Fig. 22 (b) is rolled from the right to the left. In this case, the pressure roller brush 10 is wound while the coating material is not being discharged. If the coating material is discharged, the amount of discharge coating material is considerably small. As a consequence, of the wide area A1, the areas still not covered, which are both ends of the wide area, are covered. In this case, it is of importance that as in the case of the long area (6), the brush for coating rollers supplied under pressure 10 is wound while the coating material is not being discharged, and if it is discharged, the amount Discharge lining material is considerably small. In the vertically adjusted long area (7), the coating robot 171 pushes the pressure-fed coating roller brush 10 in the lowest position, and the pressure-fed coating roller brush is wound from the bottom towards the upper part while the coating material is not discharged (if the coating material is discharged, a considerably small amount of coating material is discharged). - 1 17 - Also in the uncoated area (8) in the wide area A1, the coating robot 171 pushes the platen roller brush supplied with pressure 1 0 in the lowest position, and the brush for coated platen rollers pressure is rolled from the bottom to the top or from the top to the bottom while the coating material is not discharged (if the coating material is discharged, a considerably small amount of coating material is discharged) . And, the lining operation of the wide area A1 is completed. The coating results of the coating formed in this way by the third invention were examined. The result was as shown in Fig. 26 (b). In the figure, (a) of Fig. 26 is a longitudinal sectional view showing a middle part stage of the lining of the long areas (1) to (6) is completed, and (b) a final stage that the long areas (7) and (8) vertically adjusted, it is complete. In the case of (a), the brush for coating rollers fed under pressure on the central part of the rectangular area. A thickness d3 of the coating film is thin. In the final part of the rectangular area, the brush for coating rollers fed under pressure stops. According to the above, a thickness of the coating film is thick. In this way, the thickness of the coating film is not uniform. In the invention, thereafter, the roller is rolled-over a part of a thickness d3 (long area (7) and a portion of a thickness d1 (i.e., long area (8)) in a state which does not discharge the coating material to flatten such parts in such a way that the thickness part d 1 expands, such that the coating film P2 becomes uniform in thickness over the entire area thereof. thicknesses d4 and d6 at both ends of the coating film, and the thickness d5 of the central part thereof are made equal, as shown in (b) .Thus, in the third invention even if the material of Paralyzed coating is formed, the flattening operation: by the empty roller is performed in the next stage According to the above, a thickness P1 of the coating film is uniform, and from there, the buckling caused by the coating material paralyzed is removed, in the rev method As described above, only in the coating of the final long area (6), the brush for pressure-fed coating rollers is wound while the coating material is not discharged. In doing so, the thickness of the coating film is not increased at both ends of the long area (6), while the coating film is thick at the ends of the long areas (1) to (5) in the method of conventional coating. When the pressure-fed coating roller brush flattens the portions of the increased thicknesses d 1 and d 2, while moving from the lower part towards the upper part or from the upper part to the lower part, and reaches the - 1 - final long area (6), this long area does not include the parts of the thicknesses d 1 and d 2, and from there, it is not necessary to uniformly expand the coating film, and the thickness of the uniformity process stage is terminated. A width of the uncoated area is determined by a quantity of paralyzed coating material formed in the pre-stage. For example, as the amount of paralyzed coating material increases, the width of the uncoated area expands, and when it is small, the uncoated area is narrow. The width of the uncoated area should be shorter than that of the coating roller fed under pressure, as a course material. If the coating width overlap is excessive, the coating efficiency (time) is reduced. 10% overlap is preferred. For example, the overlap width is preferably approximately 20 mm when the coating width is 170 mm. The coating conditions in an example where the current coating method is used are: Pressure roller coating weight: 0.6 to 1.5 kgf (8.8 to 147N) Coating width: 1 70 mm (7 inches brush) for rod wheels) Superposition width: 10 to 50% (10% = approximately 20 mm) - 120 - Roller linear speed: 10 to 40 m / min. Roller coating direction: right direction. Fig. 27 is a plan view showing three examples of the parts of a car to which the coating method of the third embodiment can be applied: Fig. 27 (a) shows a cover; Fig. 27 (b) shows a roof; and Fig. 27 (c) shows a trunk. The following facts are commonly applied to Figs. 27 (a) to 27 (c). In the long area of the uppermost line ((6) of the roof, (9) of the roof, and (4) of the trunk) and the long areas? vertical on both ends ((7) and (8) of the roof, (1 0) and (1 1) of the roof, and (5) and (6) of the trunk), the brush rollers for coating rollers pressure fed while the coating material is not being discharged or a considerable amount of coating material is discharged In other long side areas to the above, the pressurized coating roller brush discharges the coating material , and the pressure-fed coating roller brush is rotated on each feeding line, and returned to the original position.The advantages that result from the roller operated in this manner are as described above. The roof and the trunk include curved surfaces in addition to the flat surfaces.Where conventional coating rollers are used, it is impossible to automate the coating process. of coating 171 with the coating rollers supplied by pressure (Fig. 22) of the invention presented by the Applicant of the present Patent Application allows the coating process to be automated. To coat the parts where the roller is not flowable for the surface configuration, for example, the area A2 different from the wide area A1 in Fig. 26, the worker is completely covered by the use of the brush or the roller. Alternatively, to the complementary coating work, a small roller more manageable than the pressure-fed coating roller is used or a? slotted nozzle that produces little dust and a clear edge of the spraying model of the coating material is attached to the coating robot. Fig. 28 is a plan view of an example of unr. Effective coating process by using the coating robots 1 71 and 172 shown in Figs. 25. The coating robot 1 causes the pressure fed coating roller 171 to cover only the cover by the coating method of the third invention as in the case of the wide area A1. At the same time, a coating robot 2 causes the pressure-fed coating roller 172a to scan the areas of the trunk towards the ceiling by the coating method of the third invention as in the case of the area A2. To effect an effective coating, it is preferable that the automobile moves, and the coating rollers 1 and 2 are also moved in bond with the former. As described above, according to the third invention, there is no need for manual work for the coating by the roller coating. Accordingly, the coating material is uniformly applied to the entire roller, and hence, the non-uniformity of the coating film thickness does not occur. There is no need to repeat such a process that the coating material is applied to the roller several times, and thus the coating material again infiltrates the roller. This advantageously results in the reduction of labor cost and labor hours, and the coating booth. A coating production is improved. In particular, the coating method allows a coating process to uniform the thickness of the coating film over the entire area a *. automate In addition, the roller-type automatic coating apparatus according to the present invention can be applied to the coated objects that have been coated by the use of the roller, without any limitation. The specific examples of those objects are objects concerning vehicles and construction, boats, furniture, and objects concerning roads. The coating material used by the third invention is not limited to the coating material that is conventionally used by the known roll coating process, but may be an aqueous coating material, an organic solvent coating material and the like. . While the invention has been described in detail by using some specific embodiments, it should be noted that the invention is not limited to those embodiments, but it can be modified variously, altered and changed within the true spirits and scope of the invention.
